- Cybersecurity experts including Joshua Corman, Sophie McDowall, and Rob Denaburg told The Verge that human attackers using AI as a force multiplier — not rogue AI agents — remain the dominant cyber threat to US energy infrastructure.
- Much of the US energy grid was never designed for internet connectivity: the average American nuclear reactor is about 44 years old, and some original equipment manufacturers have gone out of business, leaving orphaned devices with no one to develop software patches.
- Operational technology systems controlling physical machinery are often designed to apply updates only once per quarter or year, and smaller utilities frequently lack the staffing and resources to deploy advanced defenses, according to the Foundation for Defense of Democracies.
- OpenAI pledged $1 billion on September 3 toward subsidizing training and access to new models intended to help defend critical infrastructure, even as CEO Sam Altman met with utilities to discuss securing power grids.
- Sophie McDowall of the Foundation for Defense of Democracies criticized AI developers for "offering support for a problem that they are partially causing" while failing to adequately control their own technology advancements.
- Utilities are increasingly turning to a "disconnect it" approach — pulling systems offline when they can't be protected — and ensuring infrastructure can switch to manual operations, per Corman at the Institute for Security and Technology.
- Unlike nuclear technology and hazardous materials, AI development currently lacks comparable regulatory guardrails despite its potential risk to critical infrastructure and human life, McDowall told The Verge.
Why it matters: US utilities face a structural disadvantage: 44-year-old nuclear reactors and orphaned devices cannot be patched as quickly as AI-equipped attackers adapt, and OpenAI's $1 billion defense pledge comes from a company critics say is 'partially causing' the threat. The gap between offense and defense is widening even as AI lacks the regulatory oversight applied to comparably risky technologies like nuclear power.
